She heard you and is acting up. You hurt her feelings.....

Update. Just for laughs ran a compression test. All cylinders 175psi but one. 130 psi. Not knowing these engines that well I would say head gasket or a possible burnt valve. Ideas?

Her feelings have not yet begun to hurt. Spraypaint a quick target on her hood and dump a couple clips of.300 Blackout

Nah, M855/SS109. Those things will zip right through an aluminum block.

Oh, and here ya go, from my 2003 manual:

I was getting the same p1320 code, did the idle test by unplugging each coil one at a time. Rears had a change in idle for each one, the front, all 3 no change. I replaced them with OEM used coils I got from Smelly Fart here on the Org ( thanks Leonard ) and problem solved. Get OEM coils, you may get anyway with aftermarket but its hit or miss.

Do the balance test I mentioned above and see if you get a change in idle like someone else mentioned above.. the code you're getting is related to coils and nothing else.

Sounds like I need to invest in OEM coils and MAF. Anyone know where I can get these without breaking the bank?

Coils I have bought before are:

HITACHI IGC0012 {Click Info Button for Alternate/OEM Part Numbers} Info
Right; Actual OE Part; Terminal Quantity: 3; Mount Type: One Bolt; Coil on Plug Ignition; Terminal Gender: Male; Terminal Type: Blade; Voltage: 12


From Rockauto. They are apparently the actual factory part.



Could you find out what brand of coils your son got from Rockauto?



I'm going to look over this thread again tonight to see if anything else comes to mind.

Nevermind I was just on a boring call so here's the summary if this thread as I understand it, with three questions:

Issue: Sometimes when braking the idle goes below 500 rpm and it stalls.

Possible solution: clogged Idle Air Control Valve

You cleaned throttle body and iacv. Ran great when you test drove it, wife says it’s acting up again.

Question 1: are you finding then that the issue is intermittent if it ran great for you but not for your wife? Or does it happen all or most of the time?

Codes at this point:
PO320 ignition signal primary
PO110 intake air temp sensor 1 circuit 3.
PO120 Throttle/pedal position switch A.

You replaced MAF with aftermarket
You replaced Ignition condenser

"Still getting PO320 ignition signal primary"

But then you mention "not showing misfire codes but still p1320 code."

Question 2: Can you confirm if the code is P0320 or P1320?

Then you mention: "Just for laughs ran a compression test. All cylinders 175psi but one. 130 psi."

The minimum compression allowed is 142 psi.

Question 3: I'm curious about your intention to buy new coils when it appears you have a cylinder that is physically damaged in some manner?
